Keeping their numbers low over long periods of time is essential for Australia's biodiversity and rural industries. Infection of rabbit populations at times in their breeding cycles when there are high numbers of young rabbits which recover from RCD and are then immune for life.

This lagovirus caused a nonpathogenic infection of the intestinal tract and was given the name rabbit calicivirus (RCV). Calicivirus is the causative agent of rabbit calicivirus disease Some rabbits in cool, high-rainfall areas carry a benign virus that gives them partial immunity to the virulent calicivirus. cunicuusi ) are highly susceptible; cottontail rabbits ( Sylvilagus floridanus ) and hares ( Lepus Pet rabbits can be vaccinated against the original calicivirus but the government released RHDV2 before a vaccine could be developed to protect people’s precious pet bunnies. On one hand, it’s seen as a solution to the significant environmental damage and economic devastation caused by large wild rabbit population; but on the other, it seems this tool has a use-by-date and cannot be controlled. Your veterinarian will be able to advise you on a suitable vaccination program for your bunny. Rabbits should be vaccinated every 6-12 months against Rabbits Haemorrhagic Disease Virus (Calicivirus) to protect them against this fatal virus.

What is Rabbit Calicivirus? Rabbit Calicivirus, Rabbit Haemorrhagic Disease Virus (RHDV), is a deadly lagovirus that was accidentally released early in 1996 to control the population of wild rabbits in Australia. A similar observation was reported for a related non-human pathogenic calicivirus strain, the rabbit hemorrhagic disease virus (RHDV, genus Lagovirus). We’ve known for some time that it has been prevalent in Australia and Europe, but this rabbit has been the first confirmed case of the new strain in New Zealand. Both virus types have been deliberately released into Australia as a control method for the wild rabbit population. The illegal importation of rabbit calicivirus disease (RCD) by a person or persons unknown in mid 1997 was a major breach of New Zealand’s biosecurity. Rabbit hemorrhagic disease (RHD) is an acute, lethal disease of European rabbits (Oryctolagus cuniculus) caused by rabbit hemorrhagic disease virus (RHD virus), a calicivirus (genus, Lagovirus) that first emerged in China in 1984 in rabbits imported from Europe. This endemic form is known as RHDV1. Current research aims to help the virus stay ahead in the co Rabbit Haemorrhagic Disease Virus (RHDV), or Rabbit Calicivirus, is a lagovirus, which is highly contagious and has a mortality rate of 40-100%. In a global world there is always the chance of unwanted pests or diseases entering the country. There was extensive government and public criticism of the illegal action and the subsequent widespread dissemination of the virus by farmers. Biological control is by far the most cost effective large-scale control option for rabbits. The disease also emerged in Europe and was spread to many parts of the world Rabbit hemorrhagic disease (RHD) is an acute, lethal disease of European rabbits (Oryctolagus cuniculus) caused by rabbit hemorrhagic disease virus (RHD virus), a calicivirus (genus, Lagovirus) that first emerged in China in 1984 in rabbits imported from Europe. , 2005b).
